[Patch Request] Porting some patches for getting great performance

[NovaPixell]

In the previous issue I mentioned the server I manage. We have a large amount of entities and tile entities, it would be interesting to have patches on Pufferfish that optimize these.

Patina, a very good and stable software, in 1.17 offers these stable patches:

1. lithium-entity.fast_retrieval.patch - lithium-entity.fast_retrieval.patch
2. New-nbt-cache.patch
3. Optimize-TileEntity-load-unload.patch
4. Item-stuck-sleep.patch

The third patch is very useful for servers that have high amounts of TE.

Please consider adding these patches, so that our servers will enjoy high performance!

I will only add patches if they have been proven (with proper profiling) to improve performance, and that the thing they claim to improve has been proven (with proper profiling) to be an actual performance problem.

I have not been shown evidence of any of these patches satisfying both of these requirements, so they will not be included in Pufferfish.
